On a recent trip to/from Arizona, I noticed my SHO was pinging. Occurs when car under a load. Not sure if could have been bad gas (Chevron) or the desert heat (115). Another caveat here, AC was definitely blowing. I don't remember if I turned AC off to check. Engine temp was 190 degrees, 3/4 tank of gas, 1 only driver in car with 100 lbs of total cargo. Has anyone experienced pinging in the intense heat of the desert?
Im running the 93 4x tune with the ACES IV
